Firmware Update v4.6.5.8 - CBR750

I just have a firmware update v4.6.5.8 for the CBR750 from the "Firmware Update" section, but I don't find any documentation from the NETGEAR website. Is safe to update?.

 

thanks!

Re: Firmware Update v4.6.5.8 - CBR750

A lot of times they choose a smaller subset of routers to push the update to or that can get it from the manual update server. 

Its usually been tested pretty well in house.

so is it safe? Tough to say unless you've tried it. 

You could make a backup configuration of your current setup. 

If it has issues, you can downgrade and restore your backup.

Re: Firmware Update v4.6.5.8 - CBR750

Thanks Plemans,

 

I'm going to give my experience with this new update V4.6.5.8_2.0.54:

  • I updated yesterday night, so, just few hours with the new update, everything looks good. Yesterday, when I was doing some speed tests after the update I was getting around 750 Mbps (I have Xfinity 900 / 20), today I am getting 930 Mbps, yesterday I had the ethernet cable with TV streaming video, so, probably the speed test was affected for that, or just with too much network traffic in the area at that moment, so, good speed now, and good latency, 0 complaints.
  • I noticed that with the v3.2.16.9_1.4.7 I had before the update I had too much correctables, and uncorrectable values. I spoke with Xfinity weeks ago to solve the issue but they were always telling me that the signal was good (one of the technitians came even one day to check). But, even with these theoric bad "values", I didn't have any real issue with internet / connection. Now with the V4.6.5.8_2.0.54 I don't have uncorrectables and just few correctables, almost nothing, that it's a good thing, probably the firmware was helping with the signal / estability.
  • The NTP Settings (Network Time Protocol) was wrong, it said that the Current Time is Thursday, 09 Sep 2021..., so, I choose a new NTP server instead of the default NETGEAR NTP server, applied changes, and next I came back to the default one and now everything looks good with Wednesday, 03 Nov 2021. The thing I don't understand is why the time is one hour less...., but, anyway, nothing to be worry about.

 

I'll update with new information if I see any issue, but, for now looks pretty good, and stable.

After a couple of days with the new firmware, I'm pretty happy with the stability and speed in general. No issues detected, and no downs.
